Design and Management of Renewable Energy Systems for Isolated Communities with No Grid ConnectionAbstract The growing demand for energy and the need to reduce dependence on non-renewable sources have driven the research and application of sustainable technologies. In this context, an integrated solution that combines distributed energy generation from renewable sources, such as wind and hydro, with effi [...] 79 551 |
Experimental Study and Kinetic Modeling of Agro-Industrial Wastes for Conversion to Fuel Gas via the Boudouard ReactionAbstract Independent parallel reactions (IPR) and distributed activation energy (DAEM) kinetic models were developed and compared for the combined pyrolysis-gasification of two agro-industrial waste materials. The aim was to recycle greenhouse gas carbon dioxide for mitigating emissions, to evaluate the ther [...] 162 838 |
Optimization of Heat Transfer in Parabolic Trough Collectors Using Advanced Turbulator Designs and Nanofluidsby
Mohsen Pourfallah
and
Ethan Languri
Abstract Parabolic trough collectors (PTCs) are essential for solar thermal energy systems, and their thermal efficiency can be significantly enhanced using turbulators and nanofluids. This numerical study introduces three novel fin-spiral turbulator configurations (4, 7, and 10 blades) to enhance heat trans [...] 219 1359 |

Quantification and Comparative Analysis of Environmental Factors to Large-Scale Solar Plant’s Energy Performance via Regression and Linear Correlation Modelsby
Jazael Ballina
and
Yun Ii Go
Abstract Performance degradation, including system deterioration, corrosion, and energy loss in solar PV systems, can be caused by environmental conditions such as high humidity, frequent rainfall, and temperature swings in tropical nations. Over the years, photovoltaic energy has been successfully developed [...] 174 1363 |
High Data Rate MWD Mud Pulse Telemetry – From Mysteries to DiscoveryAbstract Our new approach to MWD mud pulse telemetry offers significant increases over conventional data rates. Using waveguide acoustics, we show that common drilling communications channels support carrier frequencies exceeding several hundred Hertz. Such signals are prone to attenuation over large drill [...] 310 2143 |
Post-Combustion CO2 Capture from an Industrial Power Plant Using Five Chemical Solvents: A Comparative TEAAbstract CO2 capture processes using five chemical solvents were modeled in Aspen Plus V.12.1 for the capture of more than 90% CO2 from a 456 ton/hour split flue gas stream containing 12.02 mol% CO2 emitted by the Longview 780 MW power plant (West Virginia, USA). Since the flue gas contained 33.10 ppmv SO2 a [...] 385 1529 |
Stability Improvement of Multimachine System Using Back-To-Back ConvertersAbstract As the penetration level of inverter-based generators continues to increase, it becomes crucial to reduce power oscillations between inverters and synchronous generators (SG) to improve system stability. This paper uses a multimachine system as the research platform and proposes a grid separation me [...] 216 1246 |

Abstract Hydrogen is crucial in various industrial sectors and can be obtained through different synthesis routes. However, a significant portion of its production still relies on chemical processes involving fossil fuels, resulting in hydrogen and the generation of greenhouse gases (GHGs) as the final bypro [...] 271 1664 |
Nanostructure-Based Solid-State Energy Storage through Hydrogen Trapping in Batteries Using Materials Modelling TechniqueAbstract A comprehensive investigation on hydrogen grabbing by SiO-GeO was carried out, including DFT computations at the CAM-B3LYP-D3/6-311+G (d,p) level of theory. The data shows that if silicon elements are replaced by germanium, the H-grabbing energy will be ameliorated. Electromagnetic and thermodynamic [...] 222 1289 |
